Video multicast using unequal error protection with Luby Transform codes
نویسندگان
چکیده
In a recent work, we proposed a method for unequal error protection with Luby Transform codes and showed that it achieves lower bit error rates than a state of the art technique when the information symbols are partitioned into two protection levels (most important and least important). In this paper, we apply our previous work to the problem of video multicast with heterogeneous receivers. We provide simulations for the scalable video coding (SVC) extension of the H.264/AVC standard and show that our unequal error protection method provides significantly better objective video quality results than two state of the art techniques in applications where a high video quality is desired.

Unequal error protection using LT codes and block duplication
Luby Transform (LT) codes are powerful packet erasure codes with low encoding and decoding complexity. We provide a simple method to improve the bit error rate performance of LT codes. Moreover, we exploit our method to design a new approach for unequal error protection with LT codes. We used simulations to compare our approach with a state of the art unequal error protection technique when the...
متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
متن کاملOptimized cross-layer forward error correction coding for H.264 AVC video transmission over wireless channels
Forward error correction (FEC) codes that can provide unequal error protection (UEP) have been used recently for video transmission over wireless channels. These video transmission schemes may also benefit from the use of FEC codes both at the application layer (AL) and the physical layer (PL). However, the interaction and optimal setup of UEP FEC codes at the AL and the PL have not been previo...
متن کاملDistributed LT Codes with Unequal Error Protection
In this paper, we present a method to provide unequal error protection (UEP) for distributed sources in a two-source single-sink relay network scenario. A simple yet efficient technique to decompose the Robust Soliton Distribution (RSD) into two entirely different distributions by utilizing the concept of deconvolution is presented and these two different distributions are used at two different...

We study improved degree distribution for Luby Transform (LT) codes which exhibits improved bit error rate performance particularly in low overhead regions. We construct the degree distribution by modifying Robust Soliton distribution. The performance of our proposed LT codes is evaluated and compared to the conventional LT codes via And-Or tree analysis. Then we propose a transmission scheme b...
